Riverside travel trailers.

pretty much an entry level unit, built like they all are. Nothing wrong with it, made by Adventure mfg which also made the Timberlodge, an odd wedge shaped TT that was very high in the back due to a loft area. I think Adventure is out of business now, someone correct me if I'm wrong. There is also a trailer co. called riverside which may be the maker of yours, look at vin sticker to see. They advertise aluminum sided trailers only, claiming they are better than fiberglass which is an age old debate with pros and cons on both sides.
